DNA Damage Response and Metabolic Disease

Accumulation of DNA damage has been linked to the process of aging and to the onset of age-related diseases including diabetes. Studies on progeroid syndromes have suggested that the DNA damage response is involved in regulation of metabolic homeostasis. DNA damage could impair metabolic organ functions by causing cell death or senescence. DNA damage also could induce tissue inflammation that disturbs the homeostasis of systemic metabolism. Various roles of molecules related to DNA repair in cellular metabolism are being uncovered, and such molecules could also have an impact on systemic metabolism. This review explores mechanisms by which the DNA damage response could contribute to metabolic dysfunction
